Zhongxing Xu fee455fcf5 Revert r118991.
Elidable CXXConstructExpr should inhibit calling destructor for temporary 
that is copied, not the one created. This is because eliding copy constructor 
means that the object that was to be copied will be constructed directly in 
memory the copy would be constructed in.

John McCall 83fe49d1e1 Always emit full loads from volatile complex l-values.
Return the result of a complex assignment with the original values,
not by performing a load from the l-value;  this is the correct
semantics in C, although not in C++.

John McCall d764625448 Add a few more complex-related cast kinds that arise due to arbitrary
implicit conversions;  the last batch was specific to promotions.
I think this is the full set we need.  I do think dividing the cast
kinds into floating and integral is probably a good idea.

Annotate a *lot* more C casts with useful cast kinds.

Douglas Gregor 72ebdabc5d When we're type-checking the result of calling a conversion function
(while computing user conversion sequences), make sure that a result
of class type is a complete class type. Had we gone through
ActOnCallExpr, this would have happened when we built the CallExpr.

Fixes PR8425.

Douglas Gregor 44c6ee7729 Improve ASTUnit's capture of diagnostics so that the
diagnostic-capturing client lives as long as the ASTUnit itself
does. Otherwise, we can end up with crashes when we get a diagnostic
outside of parsing/code completion. The circumstances under which this
happen are really hard to reproduce, because a file needs to change
from under us.

John McCall 817d4af557 When -Wconversion computes the range of a type, it uses the (bit-)range
of the enumerators rather than the actual expressible range.  This is 
great when dealing with opaque *values* of that type, but when computing
the range of the type for purposes of converting *into* it, it produces
warnings in cases we don't care about (e.g. enum_t x = 500;).  Divide 
the logic into these two cases and use the more conservative range for
targets.

Bob Wilson aeb56444f9 Add a variant of GCC-style vector types for ARM NEON.
NEON vector types need to be mangled in a special way to comply with ARM's ABI,
similar to some of the AltiVec-specific vector types.  This patch is mostly
just renaming a bunch of "AltiVecSpecific" things, since they will no longer
be specific to AltiVec.  Besides that, it just adds the new "NeonVector" enum.

Ted Kremenek 5eec2b0bd3 Region-allocate all AttributeList objects from a factory object instead of manually managing them
using new/delete and OwningPtrs.  After memory profiling Clang, I witnessed periodic leaks of these
objects; digging deeper into the code, it was clear that our management of these objects was a mess.  The ownership rules were murky at best, and not always followed.  Worse, there are plenty of error paths where we could screw up.

This patch introduces AttributeList::Factory, which is a factory class that creates AttributeList
objects and then blows them away all at once.  While conceptually simple, most of the changes in
this patch just have to do with migrating over to the new interface.  Most of the changes have resulted in some nice simplifications.

This new strategy currently holds on to all AttributeList objects during the lifetime of the Parser
object.  This is easily tunable.  If we desire to have more bound the lifetime of AttributeList
objects more precisely, we can have the AttributeList::Factory object (in Parser) push/pop its
underlying allocator as we enter/leave key methods in the Parser.  This means that we get
simple memory management while still having the ability to finely control memory use if necessary.

Note that because AttributeList objects are now BumpPtrAllocated, we may reduce malloc() traffic
in many large files with attributes.

This fixes the leak reported in: <rdar://problem/8650003>
